Ink jet print head
Abstract:
An ink jet print head is provided which, during a suction-based recovery operation, can effectively remove air bubbles from the common ink path by producing an ink flow in the common ink path. In each of a plurality of bubble forming chambers where an element is installed to generate a thermal energy, there are provided a first ink path for leading ink directly from the ink supply port and a second ink path for leading ink from the common ink path formed on a far side of the array of the bubble forming chambers with respect to the ink supply port. The plurality of the first ink paths include those ink paths with less flow resistance than that of the second ink paths and those ink paths with higher flow resistance than that of the second ink paths.
